Tip: Fresh Mozzarella is sold in several sizes. Fresh Mozzarella perline, or “pearls” are ½-inch pieces, while ciliegine, or “small cherries” are bite-sized 1-inch balls. If using an 8-ounce ball, cut into 1-inch pieces before tossing with pasta. All sizes are usually sold packed in water in the deli or cheese section of your grocery store.
